Research published in the journal Cell Reports challenges the most popular theory about why our bodies deteriorate in old age. Scientists know that as we grow older our cells accumulate particles, called free radicals. It has long been thought that free radicals wreak havoc by damaging proteins and impairing their function – but the new research shows that proteins can survive unscathed.
After decades of overtreatment for low-risk prostate cancer and inadequate management of its more aggressive forms, patients are now more likely to receive medical care matched to level of risk, according to a study by researchers at UC San Francisco.
Although the causes of many age-related diseases remain unknown, oxidative stress is thought to be the main culprit. Oxidative stress has been linked to cardiovascular and neurodegenerative diseases including diabetes, hypertension and age-related cancers. However, researchers at the University of Missouri recently found that aging actually offered significant protection against oxidative stress. These findings suggest that aging may trigger an adaptive response to counteract the effects of oxidative stress on blood vessels.

As advances in medicine allow individuals to live longer, people are facing unique age-related health challenges. As they age, organs such as the kidneys become more susceptible to injury, and their ability to self-repair is decreased. Researchers from the University of Missouri have found a cellular signal that causes kidney cells to die, making the kidneys prone to injury. This finding could lead to improved kidney function in the elderly.
An estimated 65 percent of ischemic stroke survivors experience cognitive impairment and decline. However, little is known about the varying roles of cognitive risk and protective factors before, during and after stroke.
Omega-3 fish oil is a popular supplement because of its perceived cardiovascular benefits, but the scientific evidence has been conflicting. New research in Physiological Reports supports the claims for seniors, finding that healthy seniors who took omega-3 supplements every day had better cardiovascular health after 12 weeks of use.
Studying brain scans and cerebrospinal fluid of healthy adults, scientists have shown that changes in key biomarkers of Alzheimer's disease during midlife may help identify those who will develop dementia years later, according to new research.
New research suggests that a molecule commonly found “decorating” brain cells in higher animals, including humans, may affect brain structure. The study showed that small changes made in how sialic acid attaches to cell surfaces can cause damaged brain structure, poor motor skills, hyperactivity and learning difficulties in mice.

Adults over 50 who have persistent symptoms of depression may have twice the risk of stroke as those who do not, according to a new study led by researchers at Harvard T.H. Chan School of Public Health. Researchers found that stroke risk remains higher even after symptoms of depression go away, particularly for women.
For the past 20 years, a large portion of the particles measured in the atmosphere were missing from models. At best, models were able to explain one-tenth of the carbon-rich secondary organic aerosols measured in the air. The problem turned out to be a series of fundamental assumptions used in the models due to a lack of experimental data. All of the assumptions were proven false by Dr. Alla Zelenyuk and her colleagues.
America’s population of senior citizens is growing, and with it, a reliance on canes, wheelchairs and scooters.
